Would you say this to an ugly person? Were they trying to be mean?

You're really bringing all of this on yourself one, by your own lack of self esteem and your own negative view of your appearance, two, by being so angry and resentful because someone paid your sister a compliment and instead of being happy for her you turn it into a negative on you, which it was never meant to be, but due to your low opinion of yourself, you take everything as a personal insult. Three, you need to elevate your self esteem and not take everything as a personal insult, that will only make things worse for you than you've already made them. And they were being neither mean nor insensitive, it makes you impossible to be around.
